A sarcastic retort to anyone who goes by the name of Helen that makes a derisory comment in your direction. The phrase is delivered with a shoulder up - down movement as each syllable is uttered, thus creating the suggestion that one is both a child (or at least possesses child-like qualities) and a simpleton, with little idea of how to successfully kick someone's ass verbally. Found around the Droitwich and Leeds areas.

Helen: "Is that acne or did you swap your face for a pizza?"
Pizza Face: "Helli Ha Ha."
